Mythology, Art, Science, and Tributes to Owls 1.


The "Vegetation-Fire-Owl" Project -- Research on potential effects of forest vegetation management, and fire and fuels management, on Northern Spotted Owls in the eastern Cascade Mountains of Washington and Oregon.

     A recent update, with my interviews on owl myths in Tanzania, east Africa, with a Chagga tribal member and a Maasai village chief.

Myth of the Tawny Frogmouth 'Owl'

The strange story of the owl who called my name.  

The spirit of owls ... and Song of the Spotted Owl.  (Poetry.)

A tribute to Dr. Karel H. Voous, the man who loved owls (and who wrote an owl poem). 

     The year was 1988.  Conservation of old-growth forests and Northern Spotted Owls was a raging social and political issue in the Pacific Northwest U.S.  I was deeply embroiled in conducting one of the earliest population viability analyses of the owl (or most any species), while working on a regional environmental impact statement on owl habitat conservation.
     At the time, a fellow owl researcher sent me a Sierra Club greeting card with a Northern Spotted Owl on the cover.  At about the same time, I had dinner at a Chinese restaurant and cracked open a fortune cookie.  Its message seemed fitting for the issues of the day, so I taped it onto the front of the card and have kept it ever since

Do you conduct scientific surveys of owls?  Help contribute to a major synthesis of owl survey techniques.  Part of the Global Owl Project ("GLOW").
